Let us define place value
Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000. It is important that we understand that whilst a digit can be the same, its value depends on where it is in the number.
Given the number 1,664,963, the place values of each of the numbers are
1= 1 Million
the first 6 from the left= 6 hundred thousands
the second 6 from the left = 6 ten thousands
4= 4 thousands
9= 9 hundreds
the last 6 from the left = 6 tens, and
3= 3 units
Hence, the place occupied by 9 in the number 1,666,963 is 9 hundreds
